有些昆虫是由某些种类的蚜虫在漆树上形成的,由于它们含有丰富的单宁,因此被用于医药和化学目的。在中国地区最突出的种类是五倍子,它在漆树的有翅的轴上形成角状的瘤。华山虎有一个复杂的生活史,在华山虎和某些苔藓之间交换寄主,以及有性生殖和无性生殖(周期性孤雌生殖)的切换。我们利用定量聚合酶链式反应和RACE技术从中国对虾中克隆了β-微管蛋白基因的全长c DNA。该基因全长1606个碱基对,5‘非翻译区为251 ,3’非翻译区为15 。该基因编码一个376个氨基酸残基的蛋白质。研究了β-微管蛋白基因在两种自然条件下饲养的中华绒毛虫和越冬幼虫中的表达水平,以及在7.5 °C和18 °C条件下饲养的昆虫的基因表达水平,发现在这两种条件下昆虫的基因表达水平没有显著差异(P > 0.01)。这表明β-微管蛋白基因是高度保守的,可以作为进一步研究这种重要的蚜虫基因表达和繁殖决定的参考。
Some insect galls are formed on sumac plants by certain aphid species and have been used for medicinal and chemical purposes as they are rich in tannins. The most prominent species among gall aphids in China is Schlechtendalia chinensis, which formed horn-shaped galls on the winged rachis of Rhus chinensis. S. chinensis has a complex life cycle, with a switch of hosts between R. chinensis and certain mosses, and a switch of sexual and asexual reproduction (cyclical parthenogenesis). We have cloned a full-length cDNA of the β-tubulin gene from S. chinensis, using qPCR and RACE. This cDNA has 1606 base pairs with a 251 bp 5′-untranslated region (5′-UTR) and a 15 bp 3′-untranslated region (3′-UTR). The gene encodes a protein with 376 amino acids residues. The expression levels of the β-tubulin gene in S. chinensis were investigated among fundatrigeniae and overwintering larvae rearing under either natural conditions, or at 7.5 °C and 18 °C. No significant differences (P > 0.01) in gene expression levels were found in insects under these conditions. It is indicates that the β-tubulin gene is highly conserved and then it may be used as a reference for further research in gene expression and reproduction determination in this important aphid.
